GHANNELING AND GROOVING MACHINE.

Patented April 21, 1908.

Application filed August 1, 1902. Serial No. 117,355.

' To all whom it may concern:

CLARENCE L. EATON, a States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Ohannelin and 'Grooving Machines; the following to be a full, clear, and exact de: scription of the invention, such'as will enable others skilled in the art to which it apperthe same.

the manufacture of boots andshoes, and more particularly to machines for preparing the outsoles of boots and shoes to be secured to of welted boots and shoes.

, certain More particularly the invention relates to improvements upon the machine disclosed in Letters Patent of the United States granted to United Shoe Machinery Co. on

the 8th day of October, 1901, No. 684,359, upon an application filed by me. I

The machine of the aforementioned patent comprises certain im .roundin and channehng machines, such as disclose in Letters States No.600,883,

issued on the 22nd day of March, 1898 to W. 0. Meyer and Z. T. French and has for its object the production of a machine for rough roundingand channeling the outsoles o boots and shoes, and particularly to oertainimprovements in the whereby t e o erator ma at will, throw out ofoperation t e channeing knife, without afiecting the operation of the roundin knife, so that certain ortions of the shoe so e may berounded an channeled, and certain por tions thereof maybe rounded without channelin whereby the stitches which unite the the outsole to the A rovide a channeling machine, and particurounding mechanism,

substantially as disclosed in Letters Patent outso e tothe welt are placedupon the tread surface of the sole,

welt is known in shop parlance as stitchingaloft.. I The object of the prese'nt invention isto, arly a channeling machine embodying rough enerally known in the art as rough rounf' machines, and provided with a channeling knife which may be thrown out of operation of the United States No, 684,359, hereinbefore referred to, with a and I do hereby eclare ing a shoe solo in which the lasted upper, welt and insole,

provements in rough Patent of the United mechanism of such machines which method of uniting mg and. channeling grooving knife so combined and arranged with relation to the channeling knife, that when said channeling knife is in operation, the grooving knife is out of operation, and-when the channeling knife is out of operation, the grooving knife is in operation, acting to form a groove in the tread surface of thcoutsole in such portions thereof in which it is desired to have the stitches show. Thus while producing all the effect, in so far as the appearance of the tread surface of the sole is concerned, of those shoes wherein the, outsole is attached by stitching aloft, at the same time producthe visible stitches protected from wear. 1e present invention are to a certain extent To the above ends t conslsts of the devices am combinations of devioes-whioh will be hereinafter described and claimed.

The present invention is illustrated in th accompanying drawings, in" which I Figure 1 shows a front elevation of the upper part of a rough rounding and channeling mac 'ne embodying my improved grooving and channeling mechanism. Fig. -2 shows a top plan view of the block carr neling and grooving knives, s lines the position of the knife the channeling grooving knife 10 in in full li dld dr when out of operation, and in dotted linesthe position of thesaidknife holder 'when the channeling knife is out of opera men, and the grooving knife is In operation. Fig. 3 shows a bottom plan view of the vibrating block and its immediate mechanism,

shown in-Fig. 2. Fig. 4 shows in side elevation and partial sectional view the arts shown in Fig. 2.- tion'of the parts shown in Fig. 2. Fig. 6 shows the movable part of the clamp of the channeling knife. Fig. 7 showsa sectional view taken on the line ac-w, in Fig. 4, looking in thedirection of the arrow in said figure. Fig. 8 shows a plan view of a rounded and channeled outsole, and Fig. 9 shows a plan view of a rounded outsole having a channeled shank portion and a grooved ball and fore part.

Similar reference characters will be employed throughout the specification anddrawings to designate-corresponding parts. As illustrated in the accompanying drawing thechan knife is in operation, and the Fig. 5 shows a side e evaings I have shown the invention as incorporated in a machine for rough roundin and has been laid that is to sa subjected to pressure in a sole laying machine, which causes said outsole to approximately assume the contour of the bottom or tread surface of the last; this method of rounding and channeling outsoles being now almost universallyemployed in the manufacture of the better grades of shoes, for the reason that the con tour' of the outsole is controlled by the 'sides of the last or the position of the in-seam, and thus more accurately conforms thereto than those soles which are rounded and channeled he'- fore being laid.

,As hereinbefore stated, the machine as illustrated is substantially the same as that disclosed in the patents hereinbefore'mentioned, and comprises a frame A, a cutting plate B which bears against the upper face of the welt and against the rear face of which the rounding knife acts in making its cut, a crease ga e C, a last gage D, a-laterally reciprocating lock or carrier E for the channeling and rounding knives, a channeling knife F, and the loosely turning sole rest G against which the tread surface of the outsole is held during the operation of the machine.

As in the machine of the Patent No. 684,359, the channeling knife F is mounted in a knife carrier supported by the upper end of a spindle a arranged to turn in a bearing b formed in a casting 0, held by means of a bolt c to the lower end of the reciprocating block E. The upper end of the spindle a is provided with a guard plate 0, preferably formed integrally with said spindle, which'rests upon and is arranged to move over the 'u per end of the block E, andpreferably provi ed uponits under face with a curved groove a which is engaged by a curved rib a formed at .the upper end of the block E. he form of the guard late a) is clearly shown in Fig. 2 of'the drawing, and as shown therein, it is cut out. forming a shoulder a, against .Whici one side of the channeling knife F'is held by the knife clamp (1, shown in pers ective in Fig. 6 of the drawing. The knife 0 am d is provided with an under cut shoulder j which engages the op osite side 'i e and it is g of the shank of the channeling km caused to clamp said knife, and held in posi tion on the plate a by means of a set screw it which passes through a hole in the upper end of the spindle a and engages a threaded aperture in the knife carrier (Z. The channeling knife and 'ts method of attachment as illustrated herein, do not differ in any essential particular from the patents hereinbeforementioned. Like Patent No. 684,359, the spindle a, its guard a and the channeling knife F are arranged to, turn about the axis of said spindle a, so as to throw said knife into and out of operative position and I have arranged to support a grooving knife upon said spindle a at substantially an angle of 15 degrees with relation to the channehng knife, so that when said channeling knife shall be thrown out of operation, the grooving knife may be caused to occupy the position held by the channeling knife, and to continue the operation upon the shoe sole begun by the channeling knife, thus forming a groove extending from the channel, as clearly shown inFi 9 ofthe drawing.

The grooving kni e may be of any of the usual forms of such knives, but as shown in the drawing comprises a shank. e having at its outer end a circular cutting ortion a, andit is held to the spindle whic 1 supports the channeling knife by means of a set screw e and washer e the said screw engaging a threaded aperture e in the head of the set set screw d, which liolds the channeling knife in position.

As shown in Figs. 2 and 3 the channeling and grooving knives are so positioned with relation to'each other, that a slight turning of the spindle a Will remove the channeling knife from o erative position and place the grooving kni 'e in operative position, and vice anism is somewhat simpler than that of the atent last above mentioned, and will now e described.

To the lower end of the sJpindlea there is fastened b means of a key and a set screw f a latera ly extending arm f which arm is engaged by one end f of a spring coiled about a stud f, the opposite end of said spring engaginlg a latch f held to turn about t ie stud f. t will be seen that the end if of the spring has a tendency to throw tie arm f into the dotted line position shown in Fig. 2, thus bringing the roovin knife into its operative position, an that t ie end f 5 of said sprin has a tendency to cause the notched end 0 the latch f, which fits in a cut away groove f of the arm f, to en age 'the outer face of said arm and restrain it by the arrow in Fig. 3 will turn the spindle.

(1., and when said arm f has been moved suthciently to permit the notched end of the latch f" to engage the outer face of the arm j", the end j" of the spring will cause said latch to engage the arm f and hold the spindle a in the position shown in full lines in Fig. 2.

inasmuch as the change from a channeling to a grooving operation must he quickly made, i. have provided the latehf with a downwardly extending linger piece f", by means of which it may be quickly operated to cause it to release the arm f and permit the spring to turn the spindle (l, as hereinbefore described.

Fig. 8 shows an outer sole rounded and channeled as it may be done in a machine equipped with the )resent invention when embodied in a rounding and channeling machine.

Fig. 9 shows an outsole provided with a channel along the shank portion and a groove along the ball and forepart, as produced by -the presentmaehine.

it will, of course be obvious that if so desired, the outsole may be formed with a groove extending entirely around its tread surface, omitting the channelat all portions thereof. f i

ht is thought that the operation of the present invention has been sutlicicntly described in connection with the foregoing description of the form and arrangement of the machine illustrated in the drawing, and that a further description of its operation will be deemed unnecessary.

Having described my iii\'(tltiuli, [claim as new and desire to protect by Letters Patent ol' the t'nited States.

t. rough roundingand channeling machine, having, in t'oinbillnlinii, a channeling knife, :1 grooving hnil'e, a single support for both knives, and means for moving the support to throw one knil'e into, and the other knife out of, operation during the continued operation of t e machine, said knives being so located on said support with relation to each other-that the o eration of one knife commences immediate y upon the interru tion of the operation of the other knife, su stantially as described.

2'. A rough rounding and channeling machine, having, in combination, a channeling knife, a grooving knife, 2. single rotatable support for both knives, and means for retating the support to throw one knife into, and the other out of, operation during the continued operation of the machine, said knives being so located onsaid support with relation to each other that the operation of one knife commences immediately upon the intcrrn 'ition of the operation of the other knife, substantially as described.

3. A rough rounding and channeling machine, having, in combination, a channeling knife, a grooving knife, a rotatable sole sup port, and a rotatable spindle for carrying said sole support, said knives being supported on said spindle andadapted to he'thrown, the one, into, and the other, out of, o eration, by turning said spindle, substantially as described.

4. A rough rounding and channeling machine having, in combination, a knife support havingprovision. for a limited oscillation about a center close to the surface of the work, a channeling knife and a rounding knife mounted upon the knife support .in close proximity to each other, and means for swinging the knife carrier in one direction to throw the channeling knife into operation and in the opposite direction to throw the grooving knife into operation during the con tinned operation of the machine, the operation of one knife commencing imn'iediately upon the interruption of the operation of the other knife owing to the relative positions of the knives, substantially as described.

in testimony whereof I allix my signature, in presence of two witnesses.
